Clearly, Scaramucci could carry the show on his own, but if there are any other slated guests, perhaps their agents might look into rescheduling? No offence to Kristen Stewart or whoever it is, but anecdotes from a movie set are going to look a little wan once he has been asked what he’s been up to recently.

As you will recall, the self-styled “Mooch” shot to global attention with his scenery-chewing role for Trump. Although he was intended as a recurring cast member, the Mooch’s tenure ended up lasting just 10 days beyond the moment his shoe-lifts first did battle with the White House podium. But, although that period was technically three days shorter than the Cuban missile crisis, it is widely accepted to have been just as lively.

He began by blowing kisses to the White House press corps, leaving the briefing to continue deleting a welter of tweets in which he had described Trump as an “odd guy” with “no judgment”, as well as many even crazier ones suggesting stuff such as climate change evidence being “irrefutable”. He succeeded in his aim of getting Trump’s chief of staff Reince Priebus fired, and made an insta-legendary call to New Yorker reporter Ryan Lizza, during which, inter alia, he demanded Lizza give up his sources, revealed he was going to sack the entire White House comms team, and differentiated himself from Trump’s chief strategist by musing: “I’m not Steve Bannon, I’m not trying to suck my own cock. I’m not trying to build my own brand off the strength of the president.” Also, during these 10 days, the Mooch became a father again, although he regretted being unable to be present at the birth due to unforeseen work commitments. Still within our window, his estranged wife filed for divorce.

So whichever way you slice it, his Colbert appearance is great news for people who want something to watch while his former boss hastens the planet toward nuclear war.

As for where we might expect the Mooch to take his act, he broke a Twitter silence on Thursday to fire shots at the aforementioned Lizza, whom he seems to blame for recording the phone call. “Ryan Lizza is the Linda Tripp of 2017,” Scaramucci judged. Tripp, you will remember, was the sly confidant who covertly recorded her conversations with Monica Lewinsky, and persuaded the latter of the need to retain as evidence a blue dress Lewinsky at first believed was marked with avocado dip. Amazing how that once felt like the ultimate White House low point, yet now resembles a rarefied olde worlde anecdote you might read about Calvin Coolidge.

Anyway, back to the Mooch’s tweet. “Ryan Lizza is the Linda Tripp of 2017. And he is up at night not being able to live with himself.” Hmmm. I suspect Lizza has managed to make his peace with his totally brilliant, historically hilarious and perfectly justified scoop … but perhaps the Mooch knows best.

What else he knows best about we shall doubtless discover on Monday – and I hope there will be some indication as to what he will do next with his personal brand. If the normal modern rules were to apply, he would of course be fast-tracked into a reality TV format. Lost in Showbiz is far from fussy as to which one, though there would be a certain meta-endtimes charm to the Mooch taking over at The Apprentice. Certainly, replacement host Arnold Schwarzenegger has confirmed he will not to be returning to the show, after presiding over a Celebrity Apprentice series this year whose ratings were repeatedly ridiculed by the president (and erstwhile host).

After that – well, who knows what the Mooch could make of the springboard. Perhaps it will only have been au revoir to the White House after all. For now, Monday can’t come soon enough.
